| Research Abstract |
In this study, we examined the heredity of papilla characteristics, which determine the market value, for the selective breeding of sea cucumber. The parent and F1groups were compared, and the results suggested that the number of papilla was influenced by a genetic factor, and parent-child identification using microsatellite DNA markerswas possible. Moreover, when the papilla characteristics of domestic 8 wild populations were investigated, it was revealed that the populations of sea cucumbers found in the Uchiura Bay, Hokkaido, had the most number of papilla. The papilla length of the sea cucumbers found in Hamasaka, Hyogo, was the longest. These results yield important information for finding sea cucumbers with superior papilla characteristics foselective breeding.
